To' all whom 'it may concern:

Be it known that I, FRANK J. FARNER, a citizen of the United States,residing at Seattle, in thecounty of King and 'State of Washington, haveinvented new and u'Seful the following ijs a specification. l

This 'invention 'relatesto bottle Stoppers Improvements inBottle-Stoppers, of which or closures, its primary object being to pro-10 vide a stop er which may be conveniently a pliedan will operatetoeffectually seal t e4 bottle against eakage, andgyet may be readilyextractedwithout the use of a special form of tool.

'15 -A further object of the invention is to pro- 'vide a constructionofbottle neckand stopper, whereby the stop er upon application may beexpanded andp roove in the against displacement and to. effect ahermeticseal, and .further vto form a stopper of sufiiciently'softmaterial to'jenable it to be punctured, cut out or'extractedWithout the necessity of employing any peculiar form' of tool for thepurpose.

The inventionconsists of the features-ofconstruction, combination andarrangement ofparts hereinafter' fully described and claimed, referencebeinghad tothe accomv panying drawing, in'wl'n'ch Figure -1 is avertical transverse section through the, upper -end .of abottle necksealed by the improvedstop er. 2 isa -similar view of the-neck/,wTth-the stopper detached. Fig: 3 is'acros's-s'ectional view ofthe stopper as it Fig. 4 1s a top plan view of the same. v

Referring to thedrawing, laddesignates a 4e bottle-neck formed withv afilling and discharge passage 2 of ordinary. or -any convenientl form..Near the to .of'thispassage 1s arranged a Horizontal s oulder 3, formingV the lower wall of an annular groove 4, ,the 53 upper wall 5 of lwhichis beveled or inclined inwardly and upwardly until it intersects theWall of the passage close to or adjacent the upper end of the neck.

The stopper constituting one of the lessene tial features of' theinvention may be composed of soft metal, paper or any other suitablepliable material, or of a combination of two or more of such. materials,and is primarily cut out. in the term of a disk 6 of circular or of anyother convenient lform. This disk is crowded into .interf .lockingengagement with a 29 neck in such va manner as to e firmlyheld appearsprior to application` then shaped in any preferred-manner to upturn orroll the edge thereof, as indicated at 7, forming a stoplper of cupformand suff' ciently contracte in diameter'. tov enter the neck andfrestupon the extreme outer edge of the shoulder 3 with the rolled rim or'fiange bearing slightly-against the wall 5 and prejiecting artiallyinto the groove 4. The margina edge of the rolled flange or rim may -beturned inwardly and downwardlyinto the vmouth of 'e the cup-shapedstopper thus formed,- as indicated at 8, so as to provide an increasedextent of rolled surface to per-- outer edge of the shoulder 3, when,through the action of a suitable type of tool or machine, the rolledflange or rim is spread outwardly or expanded into the groove 4. By thisoperation the flange or rim is to a greater or less extent unrolled andcrimped until the marginal ortion 8lies close tov or in contact with theody of the fiange7, thus bringingv the stopper-into engagement with allpoints ofthe surfaces ofthe walls 3 and 5 and interlocking it securelywith the wall of the body.

The pliable character of the material of which the stopper is madeadapts it to so closely fill the groove as to hermetically seal the neckagainst the leakage of any conlined liquid or. gas, and, as theportionof the unrolled rim lying in contact with the beveled shoulder 5is reinforced by the crimped marginal edge 8, it will be apparentthatthe firm bearing of the stopperagainstsaid shoulder'efflectuallyjprevent displacement of the sto per against greatinternalpressure. A (l) course, the forrnand arrangement of the parts within thescope of the invention as ried, but the construction in general asherein shown and described is preferred for 'general use and willprovide an effective seal under all ordinary conditions. -The characterof `definedin the appended claims may bevvathe material, inaddition tothe advantages before set forth, adapts the stop er -to be punctured,cut out or extracted y impleinents" in ordinary everyday use, thusobviating the necessity of employingr a special form of extracting tool.

Having thus described the invention, what 'l Claim as new isil. A bottlestopper comprising a substantially flat body or disk ol" pliablematerial, said disk having its marginal portion beniI or rolled upwardlyand inwardly to impart to the stopper a cup-forni, die edge of therolled angular forni.

y 2. A bottle neck provided. with :in annular groove having a'horizontal 'bottoni wall and an upwardly and vinwardly beveled t-o'pWall, said Walls having their inner edges 'flush with f the inner wallof the neek, and a stopper having a rolled rim spread into the grooveand l n l crimped into triangular forni into interlocking engagementwith said walls.

3. A bottle neck-provided with an annular groeve having a horizontalbottoni wall and an upwardly and inwardly beveled top wall, anda'stopper ol' pliable material comprising fr., body or disk resting uponthe bottoni Wall and liaviiig an upwardly and inwardly rolled inner edgeprovided Willi a pendent llang'e, said edge and flange being` spreadinto tlie Qroo've and into interlocking engagementwilvli-said beveledtop wall. ln testimony whereof in presence oi two witnesses.
